Quality of service (QoS)

Downstream traffic marking
This table describes the marking applied to traffic received from the wired network by an AP
and then sent to connected wireless client stations.
Note Although the WMM specification refers to 802.1D and not 802.1p, this guide uses the term
802.1p because it is more widely recognized. (The updated IEEE 802.1D: ISO/IEC 15802-3
(MAC Bridges) standard covers all parts of the Traffic Class Expediting and Dynamic
Multicast Filtering described in the IEEE 802.1p standard.)
QoS example
In this example, a single controller provides voice and data wireless support with different
quality of service settings for guests and employees.
